FUEL SAVING DEVICE FOR INTERNAL COMBUSTION MOTORS Filed April 9, 1940 Patented May 20, 1941 FUEL SAVING DEVICE FOR INTERNAL COIMBUSTION MOTORS Enrique Nieves Bosdet, Mexico, D. F., Mexico Application April 9, '1940, Serial No. 328,789 In Mexico November 16, 1939 2 Claims.

This invention relates to a fuel saving device for internal combustion motors, and more particularly to an addition to be added to the carburator of said motors between the inlet of the detonating mixture coming out of the carburator and this.

It is known that the operation of the internal combustion motors is based on the expansion of the gas produced by the ignition of the detonating mixture formed by the air and the gasoline, and that there is always a waste of gasoline owing to the incomplete mixture of this fuel with the air however much has already been obtained with the advancement of the modern carburators.

The device subject of this invention has for its object to get a better mixture of the gasoline with the air after these elements have passed through the carburator in the proper proportions.

The features of the device become apparent in the following description as well as in the attached drawing as an illustration of the former, the same reference figures serving to show the same parts in the four figures shown.

In the drawing:

Fig. 1, is a lateral view in elevation of the assembly that constitutes the present device.

Fig. 2 is a plan View of the same device in which more clearly appears the shape of the common joint or separator by means of which the device is set up between the inlet of the motor and the carburator.

Fig. 3 is a sectional elevation view of the assembled device on a plan through the line A-B 1 in Fig. 2. This figure is illustrated in enlarged size in order to show more accurately the interior parts thereof; the other three figures shown in a proportionate size.

Fig. 4 is a plan view of the same device, but showing its rear part.

Such as shown in the attached drawing, the device consists substantially of a cylindrical tubular housing 5, open at both ends, provided with a flange 6 integral with said housing as shown more clearly in Fig. 3 of the drawing, said flange has the shape the inlet of the carburator generally has, that is, it extends laterally to each side and is provided in said extensions with the borings I through which the screwed bolt (not shown) passes and by means of which the device is attached between the inlet of the motor and the carburator of the car.

Fixed by means of screws or rivets 8 to the side walls of said housing there are two diametral bars 9 and It! provided with two cylindrical tubular housings II and I2, located in opposite positions and in which are lodged the stubs or pivots l3 and M, the housings H and i2 are provided with the ball bearings H.

The axle l5 of the fan It is really constituted by the two tubular extensions of each one of the aforesaid pivots l3 and [4 in whose inside is lodged the springs I8 which tends to maintain them in constant contact against their respective ball bearings IT in which they turn; furthermore, as already stated, it carries a fan It that turns with said stubs or pivots l3 and I! by means of a small wing of the body I9 that enters a small groove practised longitudinally in said shaft.

The fan It can have a variable number of blades, and its dimensions as well as its separation of each other will be the most convenient according to the maximum amount of fuel that should pass into the motor.

In the lower portion of the tubular housing 5 and under the diametral lower bar 8, is located another tubular element 29 Whose ends are closed by means of two metallic net discs 2|. The lower end of said tubular element 20 is provided with a circumferential flange 22 that rests in a cutting made at lower end of the housing 5. A screw ring 23 presses against said flange 22 and keeps the element 29 in place under the diametral bar 9.

The ensemble of the device, constituted in the way described in the foregoing paragraphs, is closed through the cover 24 provided with a central perforation in which is inserted a cylindrical rod 25 with which the upper diametral bar is provided just in its center Hi; besides, it is provided at its sides with the drill holes 23 which exactly coincide with those similarly practised in the flange 6 of the housing 5.

Once the cover 24 is placed on the fiange 6 01 housing 5, the ensemble located between the carburator and the inlet for the gas into the motor is obviously understood.

The operation of the device is as follows:

The detonating mixture of gasoline and air that comes out of the carburator by the suction produced by the cylinders of the motor at first passes through the free spaces, between the wings of the fan It which turns by the gas and air current through the carburator and said current is blown by wings of the fan on turning which produces a better mixture of both elements fuel and combustion agent. The detonating mixture passes through the net 2| which the full diameter of the casing, a socket projecting from the proximate surfaces of the bar in the axial line of the casing, pivot members mounted for rotation in each socket and extenda central hub keyed on both said extensions to prevent independent rotative movement and permit free axial movement, a spring housed in the extensions and maintaining separating pressure on the respective pivot members, and an antifriction element for the pivot member in each socket, the bearing contact between the pivot members and anti-friction elements being maintained by said spring.

2. A construction as defined in claim 1 together with a unit including a tubular section fitted removably in the end of the casing beyond one of said bars, and. screens secured to the respective ends of the tubular section and extending ing beyond the socket as tubular extensions which 15 v r y of the in are aligned axially of the casing, a fan having ENRIQUE NIEVES BOSDET.
